Sandra M. Rua Ventura; Diamantino Rui S. Freitas; Isabel Maria A. P. Ramos; João Manuel R. S. TavaresIntroduction The shape or morphologic analysis of anatomical structures, such as the vocal tract can be performed from two-dimensional (2D) or volumetric acquisitions (3D) of magnetic resonance imaging (MRI). This imaging technique has had an increasing use in the study of speech production. Objectives To determine a method to perform the morphometric analysis of the vocal tract from magnetic resonance imagin...

Petrogenetic links between lepidolite-subtype aplite-pegmatite, aplite veins an...
Antunes, Isabel Margarida Horta Ribeiro; Neiva, Ana Margarida R.; Ramos, João Farinha; Silva, Paulo Bravo; Silva, Maria Manuela Vinha GuerreiroIn the Segura area, Variscan S-type granites, aplite veins and lepidolite-subtype granitic aplite-pegmatite veins intruded the Cambrian schist-metagraywacke complex. The granites are syn D3. Aplite veins also intruded the granites. Two-mica granite and muscovite granite have similar ages of 311.0 ± 0.5 Ma and 312.9 ± 2.0 Ma but are not genetically related, as indicated by their geochemical characteristics and (...
